Notes:
- Sound measured at 1m away from the center of the unit.
- Data is valid at free field condition
- Data is valid at nominal operation condition
- Reference accoustic pressure 0dB = 20μPa
- Sound level will vary depending on a range of factors such
as the construction(acoustic absorption coefficient) of par-
ticular room in which the equipment is installed.
- The operating conditions are assumed to be standard.
